ZIP System R-Sheathing ON THE ROOF!? Exterior roof insulation demystified

In this episode of the Build Show, Matt Risinger and Tim Hill, co-owner of Risinger Build, dive into the building science behind advanced roof assemblies and continuous insulation strategies. The discussion focuses on the technical reasoning for using ZIP System R-Sheathing on the roof, examining thermal performance, air and moisture control, and long-term durability. Matt and Tim explain how rooftop insulation reduces thermal bridging, stabilizes roof assembly temperatures, and improves the performance of structural members, sealants, and mechanical systems. The episode breaks down material layers, including structural roof decking, air and water barriers, insulation panels, and drainage planes, while addressing climate-specific challenges in hot regions. Viewers gain practical insight into installation methods, vapor management, code considerations, and labor efficiency, making this episode a valuable educational resource for builders focused on high-performance construction.
